Abstract
The utility model provides a pair of bone nail reset clamp forceps, which belongs to the technical field of medical devices. The structure of the pair of the bone nail reset clamp forceps comprises a main forcep arm and an auxiliary forcep arm, wherein the middle parts of the main forcep arm and the auxiliary forcep arm are connected through a hinge shaft, circular gap-shaped bone nail seats are respectively fixedly arranged at the front ends of the main forcep arm and the auxiliary forcep arm, a hinge seat is arranged on the inner side of the main forcep arm at the back part of the hinge shaft, a penetrating and connecting hole is formed on the auxiliary forcep arm at the back part of the hinge shaft, a hinge joint bolt is hinged on the hinge seat, the hinge joint bolt is arranged on the auxiliary forcep arm by penetration and connection through the penetrating and connecting hole, and the front end part of the hinge joint bolt extends out of the penetrating and connecting hole of the auxiliary forcep arm and is provided with a screwing nut. The pair of the bone nail reset clamp forceps is particularly provided with the hinge joint bolt and the screwing nut in the position of a forcep handle, so that the operating force is applied on the forcep handle; and the forcep arms can be opened and closed through the operation of the hinge joint bolt and the screwing nut in the position of the forcep handle, the traction acting force is uniform and slow, and can not cause other external force to a bone nail at the head of the forceps, so that the danger of a fracture reset operation is reduced and the success rate of the bone reset operation is greatly improved.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of nail gripper clamp that resets.
Background technology
General; The reduction of the fracture is a great difficult problem in the fracture operation; Because human skeleton is hard and have toughness; Resetting after the fracture usually can bring very big difficulty to the operation technique person, and resetting after the fracture need assist the fix bone position to make fracture restore the growth of carrying out self-regeneration with nail sometimes.In the operation because the difficulty of the reduction of the fracture; Usually be to squeeze into nail respectively at two places of bone fracture earlier; On nail, apply strength again and reset, clinically 2 tractor that adopt spiral to feed carry out the Retracting repositioning of nail more, and it can have the power of extra direction to nail when spiral is screwed; It is bigger painstaking to cause to nail, when serious skeleton is caused damage.
Summary of the invention
The technical assignment of this utility model is the deficiency that solves prior art, and a kind of nail gripper clamp that resets is provided.
The technical scheme of this utility model realizes by following mode; This nail gripper clamp that resets; Its structure comprises main tong arm and the secondary tong arm that the middle part connects through hinge, and main tong arm and secondary tong arm front end are set with circle respectively and lack shape nail seat, and the main tong arm inboard at hinge rear portion is provided with free bearing; Offer jack hole on the secondary tong arm at hinge rear portion; Be hinged with link bolt on the free bearing, on secondary tong arm, the link bolt leading section leans out secondary tong arm jack hole and is provided with screws nut to link bolt through the jack hole cross-under.
The beneficial effect that this utility model is compared with prior art produced is:
This nail gripper clamp that resets adopts lever principle, especially link bolt is set and screws nut at pincers handle place, makes operating physical force be placed on the pincers handle; The circle at binding clip place lacks shape nail seat blocks nail; Utilize the link bolt at pincers handle place to make the tong arm opening and closing with the operation of screwing nut, its action of traction power is evenly slow, can not cause other external force to the binding clip nail; Reduce the danger of reduction of the fracture operation, improve the success rate of operation of bone reduction greatly.
This nail reset gripper clamp have reasonable in design, simple in structure, safe and reliable, easy to use, be easy to characteristics such as maintenance, thereby, have good value for applications.
